Description: Open up the timer. Remove those copper plugs and cut a hole of a size of the socket of the lightbulb. Fix the socket into the timer and redo the wiring (you need some electrical engineering hack for this). Install it on the ceiling.

The timer cost about RM15 each in Malaysia. The light socket can get it from any electrical shop. Buy the Ikea energy saving lightbulb which is running on 8Watt.
